Acqua Panna Review: The pH Claim Does Not Match the Latest Report
Acqua Panna is a still natural spring water from Tuscany, owned by Sanpellegrino S.p.A., a Nestlé Waters subsidiary. It is one of the lightest bottled waters on the market at roughly 143 to 150 mg/L of total dissolved solids, which is why it reads as soft rather than mineral-heavy.
That is the useful part. The part most pages skip is that Acqua Panna’s own published figures have moved between reports, and its most recent PFAS filing with a US state regulator is from 2019, older than most of the industry.
What is actually in Acqua Panna?
Three sources publish a mineral breakdown, and they do not fully agree. Rather than pick one and present it as fact, here is what each says.
| Measure | Company report, 2020 | Company report, 2023 | Report cited by Wikipedia (2017) |
|---|---|---|---|
| pH | 8.0 | 7.66 | 8.2 |
| Total dissolved solids | 150 mg/L | — | 143 mg/L (at 180°C) |
| Calcium | 32 mg/L | 33.1 mg/L | 30 mg/L |
| Magnesium | 6.3 mg/L | 6.6 mg/L | 6.9 mg/L |
| Sodium | 6.7 mg/L | — | 6.5 mg/L |
| Bicarbonate | — | — | 100 mg/L |
The mineral figures are close enough that the variation is unremarkable for a natural spring: calcium moves by about 3 mg/L across six years, magnesium by less than 1.
The pH is the one worth noticing. The 2023 company report gives 7.66, which is not alkaline at all, it is essentially neutral. The 2020 report gives 8.0 and the 2017 figure is 8.2. Marketing copy across the web, including the version of this page we previously published, described Acqua Panna as “naturally alkaline, pH 8.0+”. On the company’s own most recent numbers, that is no longer accurate.
Natural spring water does drift, and a pH swing from 8.2 to 7.66 over six years is within the range a real aquifer can produce. The point is not that anyone lied. It is that “naturally alkaline” is being repeated as a fixed property of the brand when the company’s latest published figure does not support it.
How soft is it, compared to what?
At 143 to 150 mg/L TDS, Acqua Panna sits at the light end of the bottled water category. The comparison makes the scale obvious.
| Brand | TDS | Calcium | Magnesium |
|---|---|---|---|
| Acqua Panna | ~143–150 mg/L | 30–33 mg/L | 6.3–6.9 mg/L |
| Evian | 357 mg/L | — | — |
| Perrier | 456 mg/L | 150 mg/L | 3.9 mg/L |
| San Pellegrino | 1,109 mg/L | 166 mg/L | 49 mg/L |
| Gerolsteiner | 2,488 mg/L | 348 mg/L | 108 mg/L |
Acqua Panna carries roughly an eighth of San Pellegrino’s dissolved mineral load and about a seventeenth of Gerolsteiner’s. Its magnesium is around seven times lower than San Pellegrino’s.
US regulation requires at least 250 mg/L to label a water as mineral water. At 143 to 150 mg/L, Acqua Panna sits below that threshold, which is why it is sold in the US as natural spring water rather than mineral water. Our page on mineral water ranked by actual mineral content covers where the heavier waters land.
What about PFAS?
Acqua Panna was not included in Consumer Reports’ 2020 testing of 47 bottled waters, and it was not in the September 2025 sparkling water round either. There is no independent cross-brand figure for it.
What does exist is a regulatory filing. Vermont’s Department of Environmental Conservation publishes a list of bottled water systems that have filed a PFAS non-detect report in order to sell in the state. ACQUA PANNA SPA appears on that list with a report date of 21 March 2019.
That is a genuine regulator-facing document rather than a brand claim, and it is worth reading precisely.
| What it establishes | What it does not |
|---|---|
| A PFAS non-detect report was filed with a US state regulator | What the reporting limit was, or which compounds were screened |
| The filing was accepted for sale in Vermont | That current production is non-detect |
| A dated, checkable record exists | Any result from a lab commissioned by anyone other than the company |
The date is the interesting part. Of the 143 bottled water systems on that Vermont list, 84 filed in 2023 and 19 in 2024. Acqua Panna’s most recent filing is from 2019, which puts it among the oldest on the list. Non-detect in 2019 says nothing about a 2026 bottle, and detection limits have improved considerably since.

Why is Acqua Panna expensive?
Three things you are actually paying for, and one you probably are not.
It is imported from Italy, which puts transatlantic freight into the price of a heavy liquid. It is sold heavily into restaurants, where glass bottles and a table-service supply chain cost more than a supermarket pallet. And it comes from a single protected source rather than a municipal supply, which limits volume.
What you are not paying for is measurably better water. At 143 to 150 mg/L TDS with a near-neutral pH, Acqua Panna is a light, low-mineral spring water. That is a taste preference, not a health advantage. Nothing in its published composition makes it nutritionally superior to a filtered tap.
Who is it actually for?
Its low mineral content is the whole argument, in both directions.
If you find heavily mineralised waters like Gerolsteiner or San Pellegrino too assertive with food, a water at a seventh to a seventeenth of that mineral load will taste noticeably lighter. That is a real and consistent difference, not marketing.
If you are drinking bottled water partly for the minerals, Acqua Panna is close to the worst choice in the category. One litre delivers about 6.5 mg of magnesium against Gerolsteiner’s 108.
And if the appeal is the “naturally alkaline” claim, the company’s own 2023 figure of pH 7.66 undercuts it. Stomach acid sits around pH 2 regardless, so the difference between 7.66 and 8.2 in a glass of water does not survive the first minute after you swallow it.
What this page could not verify
Three things, stated rather than glossed over.
The widely repeated claim that the water spends 14 years filtering through rock comes from the brand and has no independent confirmation. We found no third-party source for it, so it is not stated as fact anywhere above.
The 2023 water analysis report is published on the company’s own site but blocks automated retrieval, so the figures in the table above come from search-indexed extracts of it rather than from a copy we fetched directly. Treat the 2023 column as reported rather than verified by us.
No independent PFAS measurement of Acqua Panna exists in any public cross-brand dataset. The Vermont filing is the only checkable PFAS record, and it is a company filing from 2019.
The bottom line
Acqua Panna is a light, low-mineral Italian spring water at roughly 143 to 150 mg/L TDS, which is genuinely much softer than San Pellegrino, Perrier or Gerolsteiner. If that is the taste you want, it delivers it consistently.
The “naturally alkaline” framing no longer matches the company’s own most recent pH figure of 7.66. Its only checkable PFAS record is a 2019 non-detect filing with Vermont, at a time when most of the industry has filed since 2023. Neither is a reason to avoid it. Both are reasons to buy it for the taste rather than for a health claim.
Frequently asked questions
Is Acqua Panna sparkling or still?
Still. It has no carbonation. San Pellegrino is its sparkling sister brand, owned by the same company, Sanpellegrino S.p.A.
What is the pH of Acqua Panna?
It depends which report you read, and they disagree. The company’s 2023 water analysis gives 7.66, essentially neutral. Its 2020 report gives 8.0, and a 2017 water quality report gives 8.2. The widely repeated “naturally alkaline, pH 8.0+” claim is not supported by the most recent company figure.
Is Acqua Panna a mineral water?
Not by US labelling rules. US regulation requires at least 250 mg/L of total dissolved solids for a water to be sold as mineral water, and Acqua Panna measures roughly 143 to 150 mg/L. It is sold in the US as natural spring water.
Does Acqua Panna contain PFAS?
No independent cross-brand test covers it. It was not in Consumer Reports’ 2020 testing of 47 bottled waters or the September 2025 sparkling round. Acqua Panna SPA does appear on Vermont’s list of bottled water systems with a filed PFAS non-detect report, dated 21 March 2019. That is a company filing, not an independent lab result, and 2019 is old: of the 143 systems on that list, 84 filed in 2023 and 19 in 2024.
Why is Acqua Panna so expensive?
Transatlantic import of a heavy liquid, a restaurant-focused glass supply chain, and a single protected source that limits volume. Not measurably cleaner or more mineral-rich water. At 143 to 150 mg/L TDS it is one of the lighter waters in its price bracket.
Is Acqua Panna good for babies?
Its sodium is low, around 6.5 to 6.7 mg/L, which is the figure usually cited in its favour for formula. That said, no page can clear a specific water for an infant. Formula preparation guidance varies by country and by product, so take that question to your paediatrician rather than to a bottle label.
Acqua Panna vs San Pellegrino: which is better?
They are built for opposite preferences and are owned by the same company. Acqua Panna is still and light at roughly 143 to 150 mg/L TDS with about 6.5 mg/L magnesium. San Pellegrino is sparkling and heavily mineralised at 1,109 mg/L TDS with 49 mg/L magnesium, roughly seven times more. San Pellegrino also has a published PFAS figure, 0.31 ppt in Consumer Reports’ 2020 testing, where Acqua Panna has none.
How does Acqua Panna compare to Evian?
Evian is the more mineralised of the two at 357 mg/L TDS against Acqua Panna’s 143 to 150. Both are still waters from protected European sources. Neither has an independent PFAS figure from the main cross-brand datasets.
